The electric eels are a genus, Electrophorus, of neotropical freshwater fish from South America in the family Gymnotidae. They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts. Their electrical capabilities were first studied in 1775, contributing to the invention in 1800 of the ...
An electric fish is any fish that can generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks are also electroreceptive, meaning that they can sense electric fields. The only exception is the stargazer family (Uranoscopidae). Electric fish, although a small minority of all ...
Underwater shock waves produced by the explosion stun the fish and cause their swim bladders to rupture. This rupturing causes an abrupt loss of buoyancy; a small amount of fish float to the surface, but most sink to the seafloor. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can ...
The shock can still be perceived by a person pouring a stream of seawater on the ray, [5] or handling a net in which a coffin ray is held. The fish is capable of issuing multiple shocks in a short period of time, though each shock is weaker than the last. [17]
The torpedo fish, or electric ray, appears continuously in premodern natural histories as a magical creature, and its ability to numb fishermen without seeming to touch them was a significant source of evidence for the belief in occult qualities in nature during the ages before the discovery of electricity as an explanatory mode.
Petrocephalinae. The Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), are a superfamily of weakly electric fish in the order Osteoglossiformes native to Africa. [1] It is by far the largest family in the order, with around 200 species. Members of the family can be popular, if challenging, aquarium species.
Mahi-mahi. The mahi-mahi (/ ˈmɑːhiːˈmɑːhiː /) [3] or common dolphinfish[2] (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado (not to be confused with Salminus brasiliensis, a freshwater fish) and dolphin, it is one of two ...
Electrofishing. Scientists carrying out a population and species survey using electrofishing equipment. Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
